Section 397
As he spoke, Lu Yu took out a stone axe from the bamboo basket.
He roughly selected the area to be cultivated, and then he started to dig one by one.
Loosening the soil is an important part of cultivation.
If the soil is not renovated for a long time, it is easy to clump.
In this way, when planting cassava, the permeability of the root tuber will be reduced.
It is like sealing the root.
Only after the soil is loosened, the gaps between the soil particles will increase, and air will easily enter.
In this way, the respiration of the root cells will naturally be strengthened.
At the same time, doing so can also strengthen transpiration.
Promote the exchange of mineral elements between the root hairs and the soil.
It is more conducive to the absorption of mineral elements by the rhizome.
…
The handle of the stone axe is very long, and it is just right to be used as a hoe to turn the soil.
After a while.
After hard work.
The open space finally looked brand new.
Then, in order to remove the clods hidden in the soil, Lu Yu found a long wooden stick.
He beat it for a long time.
It took nearly an hour before it came to an end.
"Huh..."
Standing up and stretching his shoulders twice.
Lu Yu took a breath and licked his cracked lips:
"That should be enough..."
"Go drink some water first, then work on it."
After returning to the camp, Lu Yu threw away the stone axe, picked up the pot without saying a word, drank the water in it, and then slowly spoke:
"Agricultural operations in primitive society are mostly migratory agriculture. In layman's terms, it means going to a place and choosing a piece of farmland."
"In this way, the randomness of migratory agriculture will make farming operations face many problems, and how to improve the soil is one of the most important links. Festival..."
"In order to adapt to the casual farming, slash-and-burn farming came into being."
"Slash-and-burn farming is an agricultural management method left over from the Neolithic Age. Everyone should have heard of this, right? The specific operation method is to loosen the soil with a stone axe first, then cut down the dead roots and stems of trees on the ground, wait for them to dry and burn them with fire."
"The land after the fire will become very soft, and the remaining ash is just a rare fertilizer. No more fertilizer is applied after sowing, which greatly shortens the farming process."
As he spoke, Lu Yu put down the bark pot, picked up the stone axe, and walked into the jungle.
While collecting dead branches and rotten wood, he continued:
"The soil is acidic, but wood ash is alkaline. Once the two are neutralized, the nutrient effectiveness of the soil will naturally be improved."
"It works better than chemical fertilizers."
"Today, in Brazil, the origin of cassava, there are still many primitive tribes who use slash-and-burn farming to grow cassava. Don't underestimate this barbaric farming method. It has been popular in the Amazon Basin for thousands of years..."

Uninhabited island.
Burning the wasteland for farming.
Such a live broadcast is novel.
It is also novel.
After Lu Yu's explanation, such an unconventional primitive farming method finally re-entered the vision of civilization after being forgotten for thousands of years.
Everyone wants to see it.
How did Lu Yu interpret the slash-and-burn farming that dominated nearly half of the history of agricultural civilization?
"Fuck!"
"Is slash-and-burn farming still okay?"
"6666, we are about to enter the farming era!"
"Are you planting the land?!"
"Although I don't know what the anchor is talking about, it seems so awesome!"
"The No. 1 outdoor anchor in Douyu is live-streaming farming and earns tens of millions a month!"
The audience's curiosity can be understood.
It is also reasonable.
But they are just curious about these primitive technologies and have not realized the deeper meaning of them.
In the primitive society, slash-and-burn farming methods have made great contributions to the development of mankind.
No matter which world, this is an indisputable fact.
But here, due to the change in the attributes of the world, people don't pay much attention to this primitive farming.
It can be seen from the audience's reaction.
Everyone is just curious.
It feels fresh.
As for the reason, it should be that after the discourse of environmental protection and ecology entered the mainstream ideology, the technology of this "civilized society" has become more and more advanced and the culture has become more and more diverse.
The slash-and-burn farming of migratory agriculture has been labeled as the enemy of the ecological environment and has been severely criticized.
Some people even compare slash-and-burn farming with foot binding, believing that it does not qualify as cultural diversity.
But in fact, these self-proclaimed advanced people often do not know how the people they call backward survive, and how the production methods they call backward are produced!
But it doesn't matter.
Today, Lu Yu will use his actual actions to show them the wisdom and strength of his ancestors!
While talking, he picked and chose.
The bamboo basket was already full of dead branches and rotten leaves.
Just cut some more shrubs, and it would be almost done.
So, after returning to the camp.
Lu Yu immediately picked up the stone axe and cut some low shrubs near the hut.
Mixed it with dead branches and rotten leaves.
All spread on the farmland to be reclaimed.
Then.
He took a long bamboo pole and broke up these materials to cover every corner as much as possible.
"Burning the wasteland is an important part of reclamation. It must be burned thoroughly."
"If necessary, it is not too much to do it twice."
"Of course, the soil conditions here are not that bad. If you get more firewood, it should be no problem to do it once...Okay, the next thing to do is to start the fire, ignite it thoroughly, and then wait for the burning to end."
Turning back to the hut.
Lu Yu took a small piece of red-hot charcoal from the campfire and threw it on the farmland.
Although there were shrubs mixed in the firewood.
But because it was dry enough.
It was still very flammable.
In less than a few seconds.
Wisp of green smoke came out from it-
"A wisp of smoke on the mountain, a fine of 3,000 yuan at the foot of the mountain!"
"Set fire to the mountain, and spend the rest of your life in prison!"
"A puff of smoke on the mountain, a fine of 15,000 yuan!"
"In the whole Douyu, there is no other anchor who dares to farm with bare hands..."
"Anchor wants fire!"
The fire burned bigger and bigger.
After a while, the whole field was red.
During this time, in order to control the fire, Lu Yu stayed by the side.
He chatted with the audience.
He used a bamboo pole to hit the fire from time to time.
Soon.
About an hour later.
All the burning objects on the ground were burned out.
It was covered with a thick layer of ash.
"Well, brothers, it's almost done."
